There's a preview of Aliens vs. Predator multiplayer on Games On Net where they offer details on four multiplayer modes in Rebellion's upcoming first-person shooter. They discuss Deathmatch, Species Deathmatch, Domination, and Survivor, which a previous preview suggested will be the game's bread and butter. Word is: "In 'Survivor', four human controlled-marines face off against oncoming waves of AI Aliens in a frantic, tense battle in cramped quarters. Death is permanent, so if you end up as face-hugger food, it’s up to your buddies to carry the flag. Guns, ammo and health are in ample supply… but so are the wall-crawlers. Think of a claustrophobic Left 4 Dead in space and you’ll be on the right track. Friendly fire was thankfully turned off during our short test, but if you think you and your mates are hardcore, you’ll find a solid challenge if you flip the TK switch. We sampled two 'Survivor' maps – a dark, dank underground mausoleum and a dimly lit spaceship – but inevitably there’ll be more in the near future.
